by virtue of the peciently cushion a wheel of a heavy vehicle The tire in smaller for use on bicycle] such as an automobile. sizes is also designed wheels, motorcycle Wheels, and the wheels of various horse-drawn vehicles.

l'Vith the foregoing in mind, the invention will be fully understood from the following description and claim -when the same is read in connection with the drawings, accompanying and forming part of this specification, in which: Figure 1 is a longitudinal section 'of a tire constructed in accordance with my invention, and properly arranged relative to a. wheel rim. Fig. 2 is a transverse section showing. the core, the wheel rim and the tire casing in section. Fig. 3 is a detail section taken on the'line 3 3 of Fig. land showing thepairs of lateral stays atthe opposite sides of each section of the core.

Similar letters designate corresponding parts in all of the views of the drawings,

' rially advantageous because the 'PIOVISlOn referring to which A is a wheel rim which may be of the typeillustrated or of any other design and construct-ion consonant with the purpose of my invention, and B is the casing of my novel tire. The said casing may be of the material generally employed for tire casings,- and may bejengaged with and held by the rim in the manner shown.

My invention resides chiefly in the core C of the tire, which core is preferably of rubber or of a composition containing rubher, though itmay be of any other resilient adapted foi'tlic use to which it is put without departure from the scope of my claimed invention.

As will be readily understoodby coinsaid invention is to its resilient core, is

parison of Figs. 13, the core C comprises a longitudinal-central bar a the inner portiona'. 6., the. portion adjacent the rim A, of which is divided by kerfs 7) into sections c, and lateral stays D, preferably two at each side of each section 0. The kerfs b are diminished in widthoutward or 'in' adirection away; from the center of the wheel, as shown, this in order to permit of suflici'ent movement of the sections o with respect of thelateralstays D is to'give shape to the tireas a whole and to prevent transverse t in the casing B;

turning of the bar a wi attention here being'directed to the fact that 1 the outer edge 0 against. the inner the core bar abears side of the tread portion of 'Casing B, whilethe innerreduced edges d of-tlie's'ections bar, are interposed'and held against trans verse movement' by the edges of the'ca'sing;

It will also be noted that the inner re need-edges d of the sections 0 bear against the outer side of the rim A, and hence serve to efiiciently cushion the the casing and retain said engagement with the edge rim. y y g I While the stays D serve the purpose stated, it willbe observed that by reason of the spaces aflorded between the stays and the sides of the core bar, the said stays do edge portions in not detract in any measure from the resiliency. .The spaces referredto are also mate thereoftends to lessen the weight of the core bar and the tire as a whole.

Having described my invention, what I a casing having bead portions arranged within said flangesand bearing against the rim, and a resilient core contained in the casing and having a longitudinal-central liar, and spaced kerfs, diminishedin width.
